Title: Improvements relating to the conveying of work pieces
IPC: B65G47/54
Filed: 1949-07-22
Abstract: 674,751. Rollerway conveyers. DEUN, S. G. (Birdsboro Steel Foundry & Macinne Co.). July 22, 1949. No. 19376/49. Class 78 (i). A transfer device for removing pieces or shapes from a rollerway approach table to one of a pair of beds positioned on either side of the rollerway includes carriages movable transversely to the rollerway tile same, each carriage supporting a. thruster consisting of a self-contained power unit and an upwardly directed plunger movable upw-aWly and downwardly by the power unit, the thruster being mounted the level of the rollerway, a dog being mounted on the upper end of the plunger, whereby the dogs when depressed can be moved to one side of a piece or shape without contacting the latter and when raised can be moved to engage the piece or shape transfer it to that bed towards which it is moving. Shapes conveyed axially along rollers 15 in the position 23<SP>1</SP> are kicked off to either side by the dog 35 which is mounted in the carriage 37 which runs on rails 39 and is reciprocated from side to side by a crank 50. Several dogs and carriages are used in practice and operated by cranks 50 from a common shaft 51. The clog 35 slides vertically in a bush in the carriage 37 and is raised and lowered bv the fluid cylinder 42 secured in a cradle fixed to the carriage. The fluid cylinders of a set of carriages are simultaneously supplied with fluid by a series of electric motor-driven pumps 43 controlled by a single switch. Shaft 51 is reciprocated by crank mechanism driven from a motor controlled in any suitable manner. The shapes are thus pushed to either position 23<SP>2</SP> or 28<SP>4</SP> by raising the dog 35 on the opposite side and reciprocating shaft 51. At these positions endless chains 25<SP>1</SP> or 25<SP>2</SP>, of which one of each is associated with each carriage, engage the shapes and convey them away to a bed, the chains being guided on rails 29 at the sides of the rollerway and over direction changing rollers 26 on the respective opposite sides of the rollerway.

Title: Improvements in or relating to beta-alkoxy monocarboxylic acids and esters of alpha-beta unsaturated acids
IPC: C07C69/54
Filed: 1947-07-21
Abstract: A b -alkoxy monocarboxylic acid is prepared by reacting a lactone of an aliphatic b -hydroxy monocarboxylic acid, having at least one hydrogen atom on the a -carbon atom with an aliphatic alcohol and optionally dehydrating to give an ester of an a -b -unsaturated mono-carboxylic acid or the lactone-alcohol mixture is heated with a dehydration catalyst to give the unsaturated ester directly.  Best results are obtained when an excess of alcohol is refluxed with the lactone or alternatively by heating in an autoclave.  A suitable solvent such as acetone may be employed as the refluxing medium when alcohols boiling above 150 DEG  C. are used.  The dehydration is carried out, preferably in the presence of a polymerization inhibitor such as copper or its salts or hydroquinone, by ordinary methods, e.g. by distillation with sulphuric acid, phosphoric acid, methane sulphonic or benzene sulphonic acid or passing the vapour over heated silica gel. Representative of b -lactones mentioned which may be employed as starting materials are those derived from b -hydroxy propionic, b -hydroxy-a -methyl butyric, b -hydroxy-isovaleric and a -methyl-b -ethyl hydracrylic acid.  Representative of alcohol starting materials mentioned are ethyl, isopropyl, myristyl and chloroethyl alcohols, tertiary butyl carbinol and ethoxy ethanol. In examples: (1) b -ethoxy propionic acid is prepared by heating hydracrylic acid lactone with ethanol and distilling the product at reduced pressure; (2) b -methoxy propionic acid is prepared similarly from methyl alcohol, the product is reacted with ammonia to form the ammonium salt.  Methyl acrylate is formed by dehydrating the b -methoxy propionic acid in examples (3) by heating with concentrated sulphuric acid and a trace of copper acetate, (4) by distilling portions from methane sulphonic acid, and (5) by slowly passing it into heated methane sulphonic acid containing a trace of copper acetate.  The unsaturated esters are useful as polymerizable materials, e.g. in the production of synthetic rubber and synthetic resins.  The b -alkoxy acids are emulsifying agents.ALSO:b -Alkoxy carboxylic acids, for example b -dodecaneoxy derivatives, are emulsifying agents.

Title: Improvements in radio direction finders
IPC: G01S1/02
Filed: 1928-07-07
Abstract: 315,990. Radio Communication Co., Ltd., and Best, F. P. July 7, 1928. Directive signalling. - The effect of quadrantal or similar asymmetric error on the true direction of the incoming wavefront in direction finding equipment is automatically compensated bv applying the necessary correcting-movement by mechanical gearing to the graduated dial across which the indicator needle moves. As shown in plan in the Figure, a frame aerial F is mounted to rotate about an axis O. An arm G is fixed to the axis O, so as to move with the frame aerial, and carries a pinion B which gears with a pinion A fixed to the framework, and a pinion C which gears with the pinion B. A pin P on the latter engages with a, radial or curved slot K formed in the graduated indicator dial D. The result is that as the frame aerial is rototed the chain of gears imparts an independent movement to the graduated dial D, the amount of which depends upon the radial distance of the point P from the centre Q. This and the shape of the slot K can be adjusted to agree with the existing quadrantal or other error. Alternatively the gears A and C can be arranged as an epicyclic pair. Or the necessary correction can be shown on a separate indicator dial.

Filed: 1974-05-08
Abstract: 1496154 Hydraulic brake actuators; wear compensation GIRLING Ltd 21 April 1975 [8 May 1974] 20369/74 Heading F2F An hydraulic brake actuator comprises a cylinder 1, a piston having an annular outer part 6 telescopically receiving an inner part 7, pre-stressed resilient means 9 between the parts capable of transmitting normal braking forces, pressure seals being provided between the outer part and both the cylinder and the inner part, and a locking strut 12 which acts between the inner part and the cylinder 1. The locking strut engages by a reversible helical thread with the inner piston part 7, has a head 13 with a clutch face 14 which is urged by a spring 18 against a normally fixed member 16 but is displaceable therefrom by an hydraulic motor 24. Should the strut 12 jam a plug 23 is removed from the cylinder 1 when a plunger 22 disengages from between peripheral teeth on the member 16 which is then rotatable on a bearing 17. In normal use a chamber 28 is pressurized to apply the brakes and the locking strut compensates for wear by rotating in the piston part 7, which is prevented from rotating by an extension 11 engaging a back plate 3, when piston displacement exceeds Ihe thread clearance. With hydrostatic brakes the brake is locked by supplying higher fluid pressure to the chamber 28 to compress the spring washers 9 when the strut rotates to engage the clutch member 16 and then releasing the pressure. The brake lock is released by pressurizing the chamber 28 again to take up the spring loading, actuating the motor 24 through a line 27 at a still higher pressure to disengage the clutch, relieving the chamber 28 and then relieving the motor 24. With power brakes pressure fluid is supplied to the chamber 28 and at a higher pressure to the motor 24 during normal braking so that the strut 12 can spin before the thread clearance is taken up to provide a smaller pad clearance than with hydrostatic braking. To lock the brake the cylinder 28 is pressurized at a high pressure to compress the spring 9. A power braking system, Fig. 2, with dual circuits to brakes at 4 wheels comprises two pedal valves FCV for service braking and two hand valves HCV which are linked to or integral with respective locking control valvesL and are used instead of the pedal valves for lock actuation. For parking the hand valves supply fluid through the pressure reducing foot valves to the cylinder chambers 28 and through the valves L to the motors 24, then relieve the motors 24 and finally relieve the chambers 28.
